SPECIFICATION :Forming part of Letters Patent No. 378,401, dated February 21, 1888.

Application filed May 29. 1885.

,To @ZZ whom t may concern;

Be itlrnou'n that we, CYRUs H. MCCORMIOK, Jr., and HENRY E. Pnrnironn, both cfChieago, in the county of Cook and State oi' Illinois, havejointly invented certain new and useful Improvements in Grain-Binders, of which the following is a specification.

In harvester-binders in which the grain is carried over the main Wheel before being deposited upon the ground it has been usual heretofore to elevate it from the platform between endless aprons or by means of toothed ralres carried by endless chains and delivering to automatic binding mechanism upon the outer side of said wheel.

In our invention We propose to locate a reciprocating binding attachment upon inclined ways between the main wheel and the inner end of the platform, dispensing with such elevator aprons or rakes, and binding the grain as the carriage traverses upward and outward tor'vard the top of the wheel, so that at the end of the outward traverse the bound sheaf may be delivered from the binding attachment directly over said wheel and fall down a chute to the ground or into a bundle-carrier; and said invention relates, mainly, to such construction and its accessory mechanism, but also to.

varionssnbordinate featn res, all as hereinafter described and claimed.

In the drawings, Figure l is a perspective view, from the Yl`ront,of a harvester-binder embodying our improvements, the platform apron being removed; Fig. 2, a top plan View with certain essential parts not shown in the preceding figure, to expose more clearly the features of our invention; Fig. 3, a rear elevation of said machine; Fig. 4,1m enlarged View in elevation, from the rear, of the binding at` tachment and tripping devices, With certain of the pinions and gear-wlieels shown in the preceding ligure omitted to expose the trippingclutch; Fig. 5, an enlarged detail in top plan of the elevating and packing drums at the inner ond of the platform-apron, and Fig. 6 a transverse section therethrough on the scale of the preceding figure.

supported in the usual manner and at the distance from the inner end of the platform-apron customary when elevatoraprons are used. From these sills rise struts or standards D, which form thesulostructure of a strong frame, D', extending from the outer side of the Wheel to a point about over the inner end of the platform-apron and steadied by a brace.l D2, from the outer end of the rear still. This frame support-s the seat D, the reel-driving shaft, and the various levers and controlling devices by which the reel-frames and the tongue are operated.

Between the niai'n.wheel and the inner end of the platform-apron is the binder-supporting frame E, having feet e, which slide upon ways e', mounted upon cross-timbers of the main frame, the outer Way, adjacent to the Wheel, being for convenience secured to the inner lateraltimber, E', of the wheelframe, and the inner way being secured to a bar, El, connecting the front and rear sills at alower elevation,

. in order that the frame shall be inclined toward the top ofthe sill. From the rear ofthe binderframe projects a rack-bar, ci, With which eugages a pinion, e, at the lower end or foot of a shaft, et, having a crank at its upper end Within convenient reach of the driver in his seat, whereby this binder-frame may beA adjusted back and forth ou its Ways to compensate for varying lengths of grain.

Attached to the binder-frame, so as to move back and forth with it, is a Wind-board, F, from which projects a bar, f, overhangiug the rear of the platform and carrying a pendent screen, F', that extends down nearly to the platform-apron and correspondsin length thereto, and which will be moved to the front or rear with the Wind-board on the binder when the binder-frame is adj usted, so as to prevent grain being cast too far back by the reel or blown o the platform by the wind. To better sustain the platform-screen and prevent sagging, its supporting-bar rests upon the upper edge of a board or cross-piece, FZ, connecting thefront and rear inner struts for the snperstructed frame, and slides thereon as on a Way in its adjustments back and forth.

Upon the binder-frame are Ways g, such as usual in the McCormick reciprocating binder,

IOO

which, like the frame itself, are directedslantingly upward toward the head of the main wheel, and upon these ways is supported the reciprocating carriage G, Carrying a frame or standard, GQ, with an overhung arm, g', in which isjournaled a rock-shaft, g2, having a binder-arm, G2, at one end and a crank, g3, at the other. Brackets on this overhung arm, also support the compressor G3 and bridge-arm G4, both of which in their peculiar relation to the binder-arm and the mode of operating them are the inventions of Henry E. Pridmore, and have been made the subject of an independent application by him iled in the Patent Office of the United States on the 16th day of March, 1885, Serial No. 159,078, and a-re here shown only for the purpose of explaining the principle of our invention, and not as being in their specific form necessary thereto.

The binder-carriage also has in its subtending arm, which passes beneath the decking or binding-table, a shaft, H, bearing a loose pinion, h, at its outer end, which meshes with a rack, H', alongside the adjacent way of the supporting-frame and is clutched to the shaft in the outward ltraverse by means of a dog, h2, so as to drive it, and through it operate the grain securing` holding, and severing devices, but is unclutched therefrom in the inward traverse, all as more fully explained in the above-mentioned application.

At the inner side of the binder-frame is mounted another shaft, I, which bears a gearwheel, l', having a. wrist-pin, t', near its outer periphery. From this wrist-pin a pitman, l2, extends to the subtending shaft in the bindercarriage and is collared thereto, so that as the wheel revolves the carriage may be alternately lpushed up the inclined ways and drawn or permitted to slide back. The pitmanhas also an upwardly-extending arm, I, which bears at its end a stud or anti-friction roller, t', entering a cam-shaped slot, i2, in and trending transversely of a link, I, which is connected to the crank from the binder-arm shaft and adjustable in length,as usual. The lower end of this link has also a slot, i3, which is, however, this time straight and nearly longitudinal, but yet slightly inclined to the length of said link,and which receives a stud or anti-frietion rollcm from the body of the pitman. The effect of this arrangement is that as the pitman is thrust against the binder-carriage and moves it upward, and its heel is gradually raised by the revolution o'f the gear-wheel to which it is con nected, the link from the binder-arm shaft is held against lateral play by the stud from the pitman entering the longitudinal slot therein, while the upper stud, or the one at the end of its branch arm, rides in the inner curved reach of the cam slot and holds it against vertical play,v or rather moves it slightly downward relatively to the rising pitman, thus keeping the binder-arm down alongside the binding mechanism until the outer traverse is completed, when the upper stud passes out of said reach-.and into the .adjoining reach, being permitted to doso by-theplay of the lower stud in the longitudinal slot, and the binder-arm and compressor are rapidly opened to release and discharge the bound sheaf. In the return traverse the binder-arm is held up or open closed by the continued revolution of the gear wheel, carrying the upper stud into the inner reach of the canivslot once more and forcing it down thereon.

For the purpose of unclutching the gearwheel from its driver, as just intimated, the usual tripping-clutch employed in the McCormick binder may be used; but we have shown one invented by Henry E. Pridmore, and iliade the subject of a patent granted him August 1S, 1885,No. 324,786,whieh is particularly adapted to the inclined movement of the binder-carriage, since a large part of the weight of the latter must be supported by the 'gearing'in the outward traverso andin the return movement as well. To form this clutch, a loose pinion, K, is mounted upon a constantly-driven shaft, 7c, in the harvester-frame. Alongside this piuion is geared a disk or cross-head, K', having studs 7c' projecting toward the pinion, and to the pinion itself,on the side facing the crosslnead, is pivot-ed a dog, K2, having a lever-arm, k2, and pressed out into normal engagement with one or the other of the drivinglugs of the cross-head by means of a spring, 7c3, se-l cured to the pinion. The engagement of the driving-lug with this dog serves to drive the pinion, and through it the gear-wheel, and move the carriage, but does not insure against either backlash or running ahead, and therefore a second dog, K3, is pivoted to the pinion in a position reverse to that of the first, and provided with teeth on its hub meshing with teeth on the hub of the other, so that whenever the first is thrown into engagement it will throw the second or locking dog into en- ICO IIO

gagemcnt also with the opposite stud and on i the same side of that stud as the engagement ofthe driving-dog with its stud. The pinion will be by this means locked positively to the cross-head and the evils referred to will be moved from contact with the lever-arm, the

IZO

dog will spring into engagemcntwith the nearest approaching lng, and the binding mechanism will be started.

From the .end or engaging portion of the latch rises an arm or finger, l, connected by a link, L', with a crank-arm, Z, from a rockshalt, Z2, to which is fixed a tripping arm or lever, L2, so arranged as to come about the center or waist of the gavel ofgrain delivered to it. Normally this arm is down, wit-h its point touching or nearly touching the decking ofthe binding-table; but as the grain is delivered to it and packed against it, by whatever means. it is forced baci: and gradually rises` rocking the shaft, and finally pushing the latch out of Contact with the drivingdog, allowing the clutch to engage to start the binding mechanism.

In order that thestarting may he determined by a greater or less accumulation of grain, as desired, thelinlt which connects the trip-latch lo the crank-arm from the tripping shaft is provided with a series of perforations, l, which enable it to belengthened orshortened between thelatch and the crank-arm, throwing the tripping arm or lever fart-her back from or bringing it nearer to the delivery-point of the grain, and permitting a greater or less accumulation of grain before said arm is actuated.

It' the tripping-latch were left to itself after the hinder had taken the gavel from beneath the tripping-arm and started on its outward traverse, the weight of said arm would carry the latch back into the path ofthe driving-dog` and this dog would strike against it the tirst time it came around and nnclutch the mechanism, probably before the traverse was halfliuished. To prevent this the latch is provided with a heel-extension, Z, having an anti-friction-roll, Zf, which, as soon as the gear-wheel is started, begins to travel on a cam-ledge, t,

` keeping them vertical, nntil finally, jnst before about the hub ofsaid wheel, thereby holding the latch away from the driving dog until the end of the return-traverse, when it falls off the end of the ledge and at once meets the drivarm emerges from its own camway tilts the ing-dog and brings the mechanism to a stop.

Above the tripping lever is pivoted a curved arm, M, the end oll which rests by its own weight or by slight spring-pressnre upon the binding-table beyond the end ofsaid lever, and which is intended to retain the gavel released by the yielding of the lever and `keep it shapely untilthe binder-arm and compressor havehad time to come down and gather it.

No special form ot' packing devices is essential to the operation of our tripping mechanism; but in order to increase slightly the elevation of the binder-flament its inner side we. have thought it preferable to employ the structure shown in Figs. 5 and 6, consisting, essentially,of a rotating drum having rocking or oscillating shafts armed with teeth, which lift the grain from the delivery end of the platform-apron and carry it up and pack it against the tri pping-lever. To more partienlarly explain this, a constantly-rotating shaft at the inner end of the platform, and herein shown as the saine shaft which carries the loose pinion or tripping-clutch, is armed along its length with disks or Spider-frames N, the end ones of which havebearings a for a series of rock shafts, N', and the middle one ot which serves to support an'd brace said shafts against sagging. At certain distances along their length these shafts have teeth a', while at one end they are provided with crank-arms 'n2 a, one of the crank-arms having a long stud, at, armed with au anti-friction roller, and the other a short lateral stud, a, which may be similarly armed, but is shown without a roller.

To the frame, at the adjacent end of the niachine, is secured a cam-plate, O, which has trackways O O'l for these studs, the latter projecting farther than' the other to catch the roller on the short stud.

Thegrain is delivered by the platform-apron A into a cradle formed by standards O, secured to the frame-worlnhaving vertical shanlts and curved offsetting arms or lingers, which at one end are in close proximity to the apron, while at the other they nearly touch the curved guide-bands OL above the drum. New, as the shaft revolves the longer roller on the crankarms of the shafts which it carries travels in the t-rackway O', and at first as it passes along the reach 0 of their traclzway, which reach is but slightly eccentric to the axis, the teeth are projected between the shanks of the cradle-fingers and then swung instantly np to' lift the grain thereon, becoming at the inoment horizontal or inclined a little upward. In this position they are carried up nearly radial to the axis of revolution until the roller arrives at the end of this reaclnwhen itenters a second reach, o', inclining inward and toward the center of the cam-plate, and therefore relatively depressing the roller and th rowing the lifting-fingers slightly bach, or rather the end of this reach, the shorter stud on the other crank-arm strikes the raised tract; o2, and as the anti-friction roller on the longer fingers back and causes them to be withdrawn from the grain without obstruction. As the fingers rock back, the short stud leaves the track o?, and the anti-friction roll on thelonger stud enters another reach, o, and swings them Still farther back or inward until their points are nearly radial to the axis of rotation, so as to be ont of the way. As the roller approaches the end of this reach, it enters a short curved extension. o5, thereof, and at that moment the stud on the opposite arm strikes a ilange, o5, serving to direct the anti-friction rolleragainst a stop-ledge, o7, immediately at the entrance of the starting-reach. This affords an obstruction or bar which oscillates the tooth-shaft and swings the short stud up and over, as shown at the foot of Fig. G, bringing the tooth again in its starting position, projecting between the shanks of the cradle-fingers.

The trajectory described by the pointot the tooth in the movements just described is in- IOS .dieated in dotted lines in the figure last .re-

ferred to. The movements of the series of teeth on the successive shaftscarry the grain up in wisps or handfuls and force it under the compression-springs I) and into thc space determined by the position of the ltrip-lever, packing it against said lever until sufficient has accumulated to form a gavcl of the dcsired size,when the pressure will cause the lever to yield, releasing the trip-latch and permitting the binding mechanism to be started. The carriage will then start on its outward traverse, the bi nderar1n will come down, carrying the band material around the gavel thus accumulated and to the grain-securing mech anism, and immediately thereafter the subtending shaft in the carriage will engage with its pinion and begin to operate said securing mechanism. At the end of the outward traversc the shcaf will have been securely bound, and as the bindcrarm rises it will be discharged over the head of the main wheel and fall down the chute or into a bundlercceptacle to be carried until sufficient has accumulated to form a gavel.
